APPARATUS FOR POLISHING KNITTING NEEDLES AND THE LIKE 4 2 Sheets-Sheet2- Filed Nov. 9, 1945 mveNTorz 72W ATTORNEY Patented Feb. 3, 1948APPARATUS FOR POLISHING KNITTING NEEDLES THE LIKE Samuel Baylin,Montreal,Quebec, Canada Application November 9, weasel-m1 No. 027,592--The invention relates to an apparatus for-polishing knitting needles andthe like as describedin the present specification and illustrated in theaccompanying drawing that form a part of the same.

Ifhe-invention consists essentially of the novel features ofconstructionaspointed out broadly and specifically in the claims fornovelty following a description containing an explanation in detail ofan acceptable form of the invention.

The objects of the invention are to devise a means for furbishingknitting needles and kindred articles in large quantities at a time; toreduce the cost in the manufacture of needles owing to less time andlabor being required in the polishing of the needles; to avoid thenecessity of a worker polishing needles individually and there in placefurnish a means for mass polishing; to speed up the production ofneedles; to increase the output of knitting needles; to construct anapparatus for the cleaning and polishing of needles that is made ofcomparatively few and simple parts, all easily assembled in the event ofrepairs or otherwise, such parts being replaceable and that will beeconomical to operate; and generally to provide an apparatus durable inconstruction and efficient for its purpose.

In the drawings:

Figure l is a fragmentary side elevation of the apparatus.

Figure 2 is a fragmentary plan view of the apparatus.

Figure 3 is a vertical sectional view as taken on the lines 3-3 inFigure 1.

Figure 4 is a vertical sectional view as taken on the lines 4-4 inFigure 3.

Like numerals of reference indicate corresponding parts in the variousfigures.

In the cleaning and polishing of knitting needles the general practicehas been to individually apply the needles to an abrasive apparatus, andthis manual operation retards production as well as losing manyman-hours, and it is therefore the purpose of this invention to providean apparatus capable of containing a large quantity of needles andoperated by agitation. An acceptable form of the apparatus is asfollows.

Referring to the drawings:

The apparatus consists of a base, as indicated by the numeral [0,suitably supported by the standards I I; on the base is mounted a gearcasing l2 and a container supporting member I3, the gear casing 12 andsupporting member 13 are provided with journal members for the intro- 2Claims. (01. 51-1164) duction of the driving shaft I4 and the axle;

shaft [5.

One end of the driving shaft I4 is secured to the end'wall of thecontainer [6 by means'of a bracket l'l, while one end of the axle shaftis secured to the opposite end wall of the container by means of bracketI 8. The driving shaft =11 extends through thegear casing t2 andterminates exteriorly of the casing into a knuckle IS, the latter beingengaged by a knuckle socket 20, the whole forming a knuckle joint. Theconnecting rod 21 has one end secured or forms an integral part of theknuckle socket 20 and the other end is connected tov the crank-shaft 22which is in turn secured to a belt pulley 23 operated by the motor 24.

The gear casing l2 forms the housing for the driving gear 25 whichengages with the splined portion 26 of the driving shaft 14. Thisdriving gear intermeshes with the gear 21 which is secured or forms apart of the driven shaft 28, the latter being connected and driven bythe motor 24 through belt pulley 29.

The container may be constructed of any suitable size or shape; as hereshown it is in the' form of a rectangular box divided ofi intocompartments 30 and having a closure or closures 31. In thesecompartments are inserted the needles to be furbished, together with asuitable abradant.

In the operation of the invention the needles to be cleaned and polishedare placed in the container with a suitable abradant, the container'isclosed and the motor started; this will cause the driving shaft torotate and as the driving shaft is secured to the container this willalso cause the container to rotate or tumble simultaneously, since thedriving shaft is also connected to a crank shaft or eccentric this willhave the effect of causing the drive shaft to move in a to-andfrodirection and in that way, the needles within the compartments aregenerally kept in alignment with one another, thereby ensuring completepolishing of the entire needle.

When the container has been agitated sumciently to accomplish thispurpose, the motor is stopped and the polished needles are removed fromtheir compartments in the container and replaced with other needles tobe furbished.

The means for holding the needles is as equally important as the meansfor agitating the same, that is to say, that the container must bedesigned and constructed in accordance with the length of the needlesthat are to be inserted therein, so that it will be impossible for theneedles, which are placed longitudinally therein, to be side walls ofthe container thereby retarding the proper polishing of the needles.

What I claim is:

1. In an apparatus for polishing knitting needies and the like, acontainer having a plurality of compartments laterally divided one fromanother which are adaptedto hold needles in'a ion-f gitudinal position,an axle shaft secured to one able bearing, a drive shaft secured to theother end of said container'and having a splined p015 p I v5.5,Thefollowing references are of record in the tion and ending in aknuckle joint, worm and drive gear means for rotating said drive shaftand container connected to said splined portion,

and concurrent means connected to said knuckle joint for impartingreciprocating motionto said container, thereby causing said needlestocontinue in sliding longitudinal relation to said container. 1' f. 2.In an apparatus for polishing knitting nee? dies and the like, acontainer having a plurality of compartments laterally divided onefromanother which are adapted to hold needles inv a longitudinal position,an axle shaftsecuredrto one end of said container and supported by asuitable bearing, a drive shaft secured to the other end ofsaidcontainer and having a spline'd portion and ending in a knucklejointlmeans com prising a power source and worm anddrive gears connectedto said splined portion for rotating said drive'shaft and container, andcrank shaft means operated by said power source and connected to saidknuckle joint for imparting reciprocating motion to said container,thereby 7 causing the saidneedles-to move in sliding ion- 10 end of saidcontainer and supported by a suita gitudinal relationto said'container.
